OLSAT Practice Pack — Grade 4

Answer Key — OLSAT Grade 4

1. 1. B — The pattern subtracts 5 each time. 22 − 5 = 17.
2. 2. E — Each step, one more shape appears each time. Continuing one more step gives E. The others: A the right figure with the wrong fill; B repeats the last figure instead of stepping on; C steps backward in the series; D the right step on the wrong shape.
3. 3. A — The relationship is "worker to their workplace." doctor → hospital, so judge → court.
4. 4. B — Each number is multiplied by 2. 32 × 2 = 64.
5. 5. E — Each step, the figure alternates big and small. Continuing one more step gives E. The others: A does not continue the series; B jumps two steps ahead; C the right figure with the wrong fill; D the right step on the wrong shape.
6. 6. B — The relationship is "action to its opposite." come → go, so throw → catch.
7. 7. C — The pattern subtracts 2 each time. 27 − 2 = 25.
8. 8. D — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives D. The others: A repeats the last figure instead of stepping on; B jumps two steps ahead; C steps backward in the series; E the right step on the wrong shape.
9. 9. C — The relationship is "member to its category." oak → tree, so sparrow → bird.
10. 10. A — The pattern subtracts 5 each time. 20 − 5 = 15.
11. 11. D — Each step, the figure alternates big and small. Continuing one more step gives D. The others: A does not continue the series; B the right step on the wrong shape; C the right figure with the wrong fill; E jumps two steps ahead.
12. 12. C — The relationship is "what it grows or turns into." cub → bear, so puppy → dog.
13. 13. B — The pattern subtracts 4 each time. 35 − 4 = 31.
14. 14. D — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives D. The others: A repeats the last figure instead of stepping on; B jumps two steps ahead; C the right figure with the wrong fill; E the right step on the wrong shape.
15. 15. B — The relationship is "animal to its home." cow → barn, so rabbit → burrow.
16. 16. D — The pattern subtracts 6 each time. 31 − 6 = 25.
17. 17. D — Each step, one more shape appears each time. Continuing one more step gives D. The others: A steps backward in the series; B repeats the last figure instead of stepping on; C the right step on the wrong shape; E the right figure with the wrong fill.
18. 18. A — The relationship is "tool to what it does." hammer → hit, so shovel → dig.
19. 19. C — The pattern subtracts 5 each time. 24 − 5 = 19.
20. 20. C — Each step, the fill moves one step through the cycle (light to dark, then starting over). Continuing one more step gives C. The others: A jumps two steps ahead; B repeats the last figure instead of stepping on; D steps backward in the series; E the right step on the wrong shape.
